Perhaps you should try some spelling variations:
"binary chain bayesian optimization algorithm" » "binary chain based optimization algorithm" (Expand Search)
"binary class path optimization algorithm" » "binary class swarm optimization algorithm" (Expand Search), "binary class based optimization algorithm" (Expand Search), "binary class whale optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary chain bayesian optimization algorithm\") OR (\"binary class path optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary chain bayesian optimization algorithm ) OR ( binary class path optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary chain bayesian optimization algorithm") OR ("binary class path optimization algorithm"))*.
